The \u201csum rule\u201d axiom is imposed on binary choice probabilities. This axiom is the same as the product rule in Luce\u2019s choice model<br \/>\n(strict utility or multinomial logit) with probabilities being added rather than multiplied. A novel version of the independence from irrelevant alternatives is imposed in multinomial choice\u2014the difference between the probability of choosing alternative A and the probability of choosing alternative B is independent from all other alternatives in a choice set. Analytical convenience of the proposed model is illustrated in application to normal form games. Additive quantal response equilibrium in two-player games is characterized by a system of linear equations that yields a closed-form analytical solution (whereas logit quantal response equilibrium often requires numerical computations).<\/p>\n<\/div>\n<div data-tid=\"messageBodyContent\"><\/div>\n<div style=\"text-align: center;\" data-tid=\"messageBodyContent\"><a class=\"btn-transparent\" href=\"https:\/\/www.ieseg.fr\/wp-content\/uploads\/2022\/10\/abstract-Pavlo-Blavatskyy.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>More<\/strong> Info<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Pavlo BLAVATSKYY MBS Date and Location &#8211; Friday October 27th 2022 from 13:30 to 14:30 in Lille campus and on Zoom &#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8211; ABSTRACT A new model of probabilistic choice [&hellip;]<\/p>\n","protected":false},"featured_media":0,"template":"","events-category":[66,166,181],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v19.2 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>[Research Seminar] IRISK: &quot;Additive choice model&quot; P.
